Port C++ router to typescript about sodium-typescript

[clinuxrulz]

Actually not sure if the Router solves the problem I am trying to solve.

I have a Stream, sa: Stream<Set<number>>, and I want to construct a stream sb: Stream<Unit> which is triggered when the Set contains a certain number. This can not be done directly with Router right? I'd need to implement something else.

I'll stick with let sb = sa.filter(set => set.contains(key)).mapTo(Unit.UNIT); for a while.

Actually Operational.split can be used with Router here to solve my problem.

Sounds like that would work. It would certainly be possible to generalize router to use a more generalized operation than equality, but it sounds like you have it sorted out.

I'll have a think about it for a while 1st. Let me know if you have any ideas of how to make it more generalized too.

Because it would be nicer in if it was in a single transaction.

maybe if the selector param returned multiple keys rather than a single key, then it could work.
